I got one of these garage door openers from 1995. I cant find the model number; Sears Best, 2 lights, 1/2HP, round green program button & chain drive. It doesn't work with any of the 2012 Buick Lacrosse 3-buttons. But I was able to find one original worn out 3-button remote (model 139.53779) that has a 12-volt battery. I was able to clear all old remotes and re-program this one remote without an issue. But still cant get the Buick to program to it. I think they were made by Chamberlain? So I guess my question is that there are different generation of Craftsman openers that can be identified by the color of the program button? So older openers wont work with the newer cars? Is there a chart somewhere that shows the different generation of openers and their compatibility?
